Larry, welcome to the forum.
Wayne said, "For myself it is a matter of relationship. My horse interacts with me in a way that reveals intelligence and "horsonality". My cat does too.
I feel the same way.
Our dogs have always been part of our family. I interact with her just as I would another person.
Now we have Tiny kitty who is an outside cat. Who knows what she eats other than the cat food I give her?
Still she is a member of the family.
